The essence of big data The above is the inevitable product of human society's data accumulation from quantitative to qualitative changes. is an important way to further upgrade and deepen on the basis of the information highway and improve the intelligence level of artificial systems, which has a great impact on the development of human society. It has extremely important influence and significance.

Big data is a very large data set with many data categories, and such a data set cannot be processed using traditional software tools. Content is captured, managed and processed. First of all, big data means large data volumes (Volumes), generally around 10TB in size. However, in practical applications, many enterprise users put multiple data sets together, forming a PB-level data volume. Secondly, there are many data categories (Variety), data comes from multiple data sources, and data types and formats are becoming increasingly rich, including semi-structured and unstructured data. Thirdly, the data processing speed (Velocity) is fast, and it can also process the data in real time even when the amount of data is very large. The last characteristic is the high veracity of data. Enterprises increasingly need effective information power to ensure its authenticity and security.

Big data is a massive, high-growth and diversified information asset that requires new processing models to have stronger decision-making power, insight discovery and process optimization capabilities.

With the widespread application of technologies such as cloud computing, cloud storage, and the Internet of Things, people obtain information, search for knowledge, and build knowledge graphs through search engines, etc.; various human social interactions and communications , social networks and sensors are also generating massive amounts of data; business automation leads to massive data storage, but effective information for decision-making is hidden in the data. How to discover knowledge from the data, big data mining technology emerged as the times require!

The relationship between big data, data mining, data analysis, artificial intelligence, big data and cloud computing. In short, I hope everyone will read more scientific articles in this area
